Describe the bug
Unable to connect the OpenBB Web App (https://pro.openbb.co/app) to my own OpenBB backend API.

My backend is deployed on a cloud server, started using:

bash
openbb-api --host 0.0.0.0 --port 6900
The backend runs fine and I can access it via browser locally (http://<server_ip>:6900), but the web app shows a 500 server error, and logs indicate a missing apps.json file.

To Reproduce
Start OpenBB backend on cloud server:

bash
openbb-api --host 0.0.0.0 --port 6900
Open https://pro.openbb.co/app

Try to connect to http://<server_ip>:6900

Error occurs with message:

Server error occurred. Please try again later or check the console logs for more details. (Status: 500)

Screenshots

Terminal ：

pgsql
Missing apps.json file

An apps.json can define custom workflows and improve user experience.
Desktop (please complete the following information):
OS: Ubuntu 22.04 LTS

Python version: 3.10.12 and 3.10.16 tested

OpenBB version: 4.4.5

Additional context
I’ve tested this on two cloud servers and one local machine – all encounter the same issue.

The backend appears to start correctly and serves the API UI, but fails to connect with the frontend.

No apps.json file found in /root/.openbb or other expected paths.

This might be a misconfiguration or missing required file for OpenBB Web compatibility.
